A group of unnatural 1-(2-deoxy-β-D-ribofuranosyl)-2.4-difluorobenzenes having a variety of C-5 substituents (H, Me, F, Cl, Br, I, CF3, CN, NO2, NH2), designed as thymidine mimics, were synthesized for evaluation as anticancer and antiviral agents. The coupling reaction of 3,5-bis-O-(p-chlorobenzoyl) 2-deoxy-α-D-ribofuranosyl chloride with an organocadmium reagent [(2,4-difluorophenyl)2Cd] afforded a mixture of the α- and β-anomeric products (α:β = 3:1 to 10:1 ratio). Treatment of the α-anomer with BF3·Et2O in nitroethane at 110-120°C for 30 min was developed as an efficient method for epimerization of the major α-anomer to the desired β-anomer. The 5-substituted (H, Me, Cl, I, NH2) β-anomers exhibited negligible cytotoxicity in a MTT assay (CC50 = 10-3-10-4 M range), relative to thymidine (CC50 = 10-3-10-5 M range), against a variety of cancer cell lines. In contrast, the 5-NO2 derivative was more cytotoxic (CC50 = 10-5-10-6 M range). A number of 5-substituted β-anomers, and some related α-anomers, that were evaluated using a wide variety of antiviral assay systems [HSV-1, HSV-2, varicella-zoster virus (VZV), vaccinia virus, vesicular stomatitis, cytomegalovirus (CMV) and human immunodeficiency (HIV-1, HIV-2) viruses], showed that this class of unnatural C-aryl nucleoside mimics are inactive antiviral agents.
